84.9 N.m at 400 V — the headline torque point
The Schneider Electric SH32053P02A1000 sits in the SH3 servo family on the SH32053P frame, a three-phase AC servo motor sized for medium-inertia loads where a multi-kW continuous duty with high peak torque is needed. Nominal torque is 84.9 N.m (751.4 lbf.in) on 115 V single phase, 74.4 N.m on 230 V single phase, 50.7 N.m on 400 V three phase and 40.2 N.m on 480 V three phase — the same winding runs cooler at higher voltage because nominal speed climbs with it, so torque trades off against speed on the speed-torque curve. Continuous stall torque is 94.4 N.m (835.5 lbf.in) across 115…480 V three phase, and peak stall torque reaches 330 N.m (2920.7 lbf.in) across the same range — the 3.5× peak margin over continuous is the reserve an integrator budgets for acceleration and shock loads at the gearbox output.
Feedback, brake, and shaft envelope
There is no holding brake on this build — any failsafe stop duty on a vertical axis has to come from the drive's brake control plus a downstream mechanical brake, since the SH32053P02A1000 itself cannot hold position when de-energised. The shaft is 38 mm diameter, 80 mm long, smooth (no keyway), mounted through an international standard 205 mm flange with a 180 mm centring collar at 4 mm depth and four 14 mm mounting holes — bolt-pattern compatible with the standard SH3 mounting footprint. Maximum mechanical speed is 3800 rpm, with maximum radial force Fr derating from 4500 N at 1000 rpm to 3120 N at 3000 rpm and maximum axial force Fa capped at 740 N — the shaft-load envelope that governs pulley, pinion and coupling selection.
Thermal envelope and cooling
Cooling is natural convection with continuous power of 10600 W — no fan, no blower, the housing sheds heat through its own surface, which simplifies panel-side integration (no ducted air supply) but caps the continuous duty at the published nominal torque rather than the higher peak stall torque. Stator resistance is 0.2 Ohm with 6.3 mH inductance, a 33.2 A continuous stall current and 136.1 A Irms maximum — the drive sizing calculation is set by the Irms figure and the duty-cycle I²t budget, not the headline nominal torque. Back EMF constant is 172 V/krpm at 20 °C — a useful sanity check for drive bus voltage selection, since the generated EMF at top speed must stay safely below the DC bus under all conditions.
Ingress, connections and machine-side fit
The motor offers either a rotatable right-angled connector or a straight connector at the electrical entry — the rotatable right-angle version is the one to spec when cable routing bends back along the motor length inside the cabinet, and it removes the need for a separate 90° cable gland. Overall length is 489 mm (19.3 in) on a 205 mm flange with 5 motor poles — the SH32053P02A1000 is a long-can frame for this torque class, so the cabinet cut-out and clearance behind the flange have to allow the full body length plus bend radius for the power and feedback cables.
Active build, quoted to order
Order quantity is single-unit packaging, with the full spec — three phase, 38 mm smooth shaft, multiturn Hiperface, no holding brake — locked to the order code; any of those four parameters changing moves the part to a different ordering suffix.
